I want to be able to record footage using my iOS device and stream it directly to a server.
There's quite a few articles on S.O. that talk about this, but I'm not sure any have answered the question very well.
Should I be using HTTP Live Streaming, or is this just for sending data to an iPhone?
Should I be using AVCaptureSession to grab the video (a segment at a time?), sending each segment to the server?
Should I be using AVCaptureVideoDataOutput and ffmpeg for streaming?
I'm a little lost with all this, so any sample code or docs or links would be really appreciated.
Thanks for your help guys.

You have to choose a network protocol for that purpose and find an appropriate media server to receive and process the stream. If the RTMP format is ok for your project, check angl library which supports RTMP streaming from iOS. Currently it's compatible with iOS 6 and 7.

I am getting a video feed in my app from a drone. The drone's SDK is giving me the video as Data or NSData into my app. I want to stream the same or divert the same to a server (for example a Wowza server). These two things should process simultanously.
You can use ffmpeg library for restreaming it.
There is a sample ffmpeg swift or objective c
I've been trying to send the video to a streaming service like YouTube for a year. The video coming into the iPad from the controller (connected to a Phantom 3 Advanced) is in H.263 format. ffmpeg is best at bulk transcoding, not a stream environment. Tried https://github.com/LaiFengiOS/LFLiveKit but it has bugs. It's a wrapper on ffmpeg that knows how to do RTMP.
The DJI go app knows how to do this, I've asked in the forum for help or code sample but they won't help. Bottom line is I can find no way to stream the video from the drone to a streaming service like YouTube or Wowza. I wish Wowza could accept H.263 native, but they site list only H.264.
So I can't give you an answer, but I can give you what I've figured out over the last year.
I'm trying to receive a live RTP audio stream in my iPhone but I don't know how to start. I'm seeking some samples but I can't find them anywhere.
I have a Windows desktop app which captures audio from the selected audio interface and streams it as ยต-law or a-law. This app works as an audio server that serves any incoming connection with that streaming. I have to say that I've developed an Android app that receives that stream and it works, so I want to replicate this functionality on iOS. In Android we have "android.net.rtp" package to manage this and transmit or receive data streams over the network.
Is there any kind of equivalent package for iOS to implement this? Could you give me any kind of reference / sample to do this, or just tell me where to start?
You can see this libraryHTTPLiveStreaming, But his protocol maybe is not standard one, You can check my fork aelam/HTTPLiveStreaming-1, I'm still working on it, it can be played by ffplay. You can try
check the file rtp.c in ffmpeg, I think it will help out
I've been searching for a while on stackoverflow and around the web for a solution to my video-streaming problem. I need to stream live video being captured from the camera (no high-quality required) from an iOS device to a remote PC in one way, i.e., the iOS device will be sending a video stream to the server/PC but not the opposite.
What appears after some googling and documentation browsing is that there are two main major standards/protocols that can be used:
Apple's HTTP Live Streaming (HLS)
Adobe's RTMP
Again, my requirement is that the iPhone/iPad will be streaming the video. From what appears on Apple's website, I understand that HLS is to be used from an encoding perspective server-side, and a decoding perspective iOS side. As of RTMP, most libraries that allow iOS streaming have commercial licenses and closed code or require you to go through their P2P infrastructure (for instance angl.tv or tokbox.com/opentok/quick-start). As of HLS, no encoding libraries seem to exist iOS side.
So my questions are:
Do you know of any SDK/Library preferably open and free that I could integrate to stream captured video from within my app?
If no, do you think developing a custom library would be a risky jungle-crossing endeavour? My guess is to go through AVFoundation and capture camera frames, compress them frame by frame and send them over HTTP. Does that sound crazy performance and bandwidth wise? Note that in that case I would need an HLS or RTMP encoder either ways.
I thank you very much in advance dear friends.

I have developed such a library, and you can find it at github.com/jgh-/VideoCore
I am updating this answer because I have created a simplified iOS API that will allow you to easily setup a Camera/Mic RTMP session. You can find it at https://github.com/jgh-/VideoCore/blob/master/api/iOS/VCSimpleSession.h.
Additionally, VideoCore is now available in CocoaPods.
I am new to multimedia and iOS programming and I came across Weborb while Googling, which provides RTMP library for iOS. It doesn't clearly mention that if it can be used to stream live video through a media server like Red5.
If any one have used this, please let me know that whether it can be used to stream live video from iPhone to a media server and where does it fit in the whole setup.
Does it act like a server itself between a media server and the iPhone application or does it also have its own media server?
I also want some links for tutorials which can help me start the real coding pertaining to RTMP streaming to a media server?
Thanks.
The short answer is yes, the RTMP library for iOS can be used with Red5, FMS, WebORB etc. The library is not the server itself, yet client. It establish the RTMP connection to the server and encodes stream before send it to the server.
As I remember the library distributive contains some example to demonstrate how streaming works. Unfortunately, the official site doesn't show any examples related to streaming, the available examples can be useful to start work with the library (http://www.themidnightcoders.com/products/weborb-for-mobile/ios-integration/rtmp-ios-examples-integration-between-java-net-and-ios.html). The documentation looks up to date - http://www.themidnightcoders.com/fileadmin/docs/ios/.
There is obviously a way to do this because so many applications are already doing it - NetCamViewer and iCamviewer to name just one.
I have searched and searched, but I'm not finding anything of value that gives a hint as to how this is done. I'm reaching out hoping that someone will give me a clue.
I'm trying to connect to an video security camera (Y-CAM), which supports the RTSP protocol, and display the video from my iPhone/iPad application. The camera has an IP address and I can view the video from a web browser and from Quicktime running on my Mac. The problem is that RSTP is not supported on iOS so even trying to connect using Safari on an iPad doesn't work.
I've read that some are trying to use Live5555, but I haven't seen an article that describes if it has been done successfully and how.
An alternative is to capture the RTSP stream on a server, convert it to an HTTP Live stream and then connect to the HTTP Live stream from iOS. Unfortunately, this hasn't proved as easy as it sounds.
I'd prefer to go directly to the camera like other applications I've seen do. the RTSP to Live is a fall back if I have to.
Any hints are greatly appreciated. Thanks!
This is wrong :) or not necessary (An alternative is to capture the RTSP stream on a server, convert it to an HTTP Live stream and then connect to the HTTP Live stream from iOS. Unfortunately, this hasn't proved as easy as it sounds.)
You should use ffmpeg library, as this library can connect any streaming server (supporting rtsp, mms, tcp, udp ,rtmp ...) and then draw pictures to the screen.. (for drawing you can use opengles or uiimage also works)
First of all, use avformat_open_input to connect to your ip address
then use avcodec_find_decoder & avcodec_open2 to find codecs and to open them (you should call them for both audio & video)
Then, in a while loop read packets from server by using av_read_frame method
When you get frame, if it is audio then sent it to AudioUnit or AudioQueue,
if it is video, then convert it from yuv to rgb format by using sws_scale method and draw the picture to the screen.
That's all.
look at this wrapper also (http://www.videostreamsdk.com), it's written on ffmpeg library and supports iOS
You really need to search stack overflow before posting , this question has been asked many times. Yes live 555 sort of works and some of us have gotten it to work..
There are other players too, including ours http://www.streammore.tv/
You can find an open source FFMepg Decoder for iOS (and somes samples) on GitHub : https://github.com/mooncatventures-group
Sample use of this library : http://sol3.typepad.com/exotic_particles/
There are two general technology to display RTSP video on iOS Safari:
RTSP / HLS (H.264+AAC)
RTSP / Websocket (H.264+AAC ==> MPEG+G.711 or H.264+?)
For HLS you can consider Wowza server.
For Websocket playback in iOS Safari you can use WCS4 server.
Main idea for websocket playback is direct HTML5 rendering to HTML page Canvas element and audio context. In the case of MPEG playback video decoding will be done on iOS Safari side using plain JavaScript.
Another option - install a WebRTC plugin with getUserMedia support and play this stream via WebRTC. Anyway you will need a server side RTSP-WebRTC transcoder in such case.
